Arranged on the shaft 69, on the exteriorl of the machine (see-Fig. is an arm 233-217 which-1s provided with a pin 231 arranged to coperate with the llatch the arm 233 being -provided at the free end with a cam shaped `member23 pivotally 'se-- cured thereto and with a coperating pin v236 for the cam-member. -Pivotally supportedat 239 is' a bell crank armv 237-.-238, lthe arm being extended as at 240 and provided with a cam roll 241. On the shaft 49 is arranged a cam member 245 arranged to coperate with the roll 241. Pivotally secured to the arm 247 is a' link 2.46 provided with ,a slot- 218 through 'which passes a pin 249 on the member or' arm 238. The. free end-of the arm 238 is pivotally secured to a' bar 250 whichvis' pivotally secured to a crank arm 251 secured tothe shaft 252, which shaft' carries the members f7 2. EachA of the members 72 is provided with a pin 259 arranged to coperate with ar member 258 secured t'o the shaft 252 (see Figs. 4 and 26). I

To prevent the operation of the totaling mechanism lor throw'the same out of opera tion when desired I` provide a vcontrolling member 260 for the pawl 51. As shown, the controlling member is slidably supported by a :lot and -pin connection 262-261 controlled by an arm 264:l coperating with a pin 263on the member 260. The arm 26l is rigidly secured to a shaft 265 'which is opera'ted bya lever 266. Any suitable-means .may be'employedfor locking the lever 266., a'latch member 26T arranged to coperate with a pin 268 lon the lever 266 being shown for the purpose (see Figs. 2 and 3).

The operation of the machine may be briefly described as follows: Referring first Ato Figs. 3. 4- and 26. Assuming the eighth key in the third order is depressed, the bar T is forced down by the pin the bell cranks 8 8 and 11-11 tm'nzg about the Centers 9 and 12. At the same time that the key is depressed the member 28 for that key is forced into the position shown in Fig. 26

by the pin throwing up the stop l31 to engage the rieten-13.27 when the same reaches the stop 3.1. It is understood o'f course that operation of anyv ofthe other keys in the se- '.little movement when the 9th keyfis det pressed and, the greatest travel of 'the bar 17 when the lirst-key is depressed. In the last instance the travel thebar 17 may be limited by thev mechanism and notneces-l sarily, by a stop member 28. Movement of the bell crank arm 11-11'carriesthe pin 25 toward the rear of the machineand the first movement of the bell 'crank tends to Anor'- mally-rotate the sector 23 onthe sector 2-1, the endof the. arm .26 normally holding its position (see Figs. 4 and26). Movement of the sector 23 moves thev arm 21 which through the bar 19 draws thebar 1T to the rear until the detent27 engages the stop 31, 'whereupon the continued movement of the key in completingv its'travel moves. the arm .26about its pivot 25,-the'sector 23 being held by the bar 17. The result is a compound lever, giving vthe movement described,

first, movement of the bar' l17. and then movement ofthe lower end of the arm 26. whichv latter movement, as is obvious, will vary with the travel ofthe bar 17. As the arm 26` is operated the arm 3l is rotated about'the shaft 33 and the 'pin 156 engaging the arm 3T raises the'bar 38.' thereby rotat-l ing the gear segment vThis rotar` the pinion 13 (see Fig. 6,) and turns the indicating.

At each movement of the .arm 31 the pawl 51 carried by the arm rotates the 'ratchet 50, therebyfthrough the pinions'52,l 56, 58,.60,"gear 61 and pinion 62, rotating-the total lindicator` wheel 63, The gear'v is` held against-'rotation by the pinion 65 with which itis in mesh and the other partslof the mechanism.v l

The item indicator wheels 45 'and total "indicator wheels 63 are normally held against a reverserotationby the' stops or pawls 66 and 67 arranged to engage th'evpins 68 on th'eindicator wheels.

thereby raising the locking member 62 so that it engages both indicator wheels and prevents overthrow of the indicator wheels and also prevents any movement ot' the same during the recording ope 'ation hereafter del scribed.

'In the'meantime thecams 178 and 177 (see-Fig. 80) .have raised the arm 170, thereby rotating the arm 168 about the shaft 169 so that the bar 165 forces .the plungers 159 back retractingthe .springs 162 where they are engaged by'theextensions 182 on'the gnravity latches 180, the pin 200 von the arm 95`having raised the members 199, thereby lowering the end 198 and permitting the latches 180 to drop. The arm v170 in raising engages the pin 187, thereby raising the bar 185 and arm 18314 lowering the cross bar 184, the arm186 being raised until the hook 191 engages the pin 188 on the member 186. Continued movementof the shaft 141 causes the roll 176 to pass over the cam face 177 5 the roll 171 having been raised, as shown in Fig. 30, so that the yarm 170 drops, the arm- 186 being still held by the hook member-189. Thearm 170 having dropped has retrieved the bar 1657 therequired plungers '159 being retained by the gravity latches 180.

If any of the type bars have not been raised either by.operation of the keys or by carrying, then the members 196 for those bars arel not raised so that the gravity latches 180 areretained up (see Fig. 8).

In this case the plungers 159 follow thevbar 165 when it is retrieved'and returned to inoperative position. If any of the type carrying arms 95 ,below a raised higher order arm are not .'aised either by operating or carrying. thereby indicating a zero or cipher. the next higher order owing to the overlapping part 1981 (see Fig. 14.-) will depress the end 198 of the neXt one or more lower ones so that the plunger or plungers will be engaged by its respective latch 180 and maintained in operative position. Further movement of' the operating handle and consequently shaft 111, brings the pin 198 on the arm 192 into engagement with the lower end of the member 189, thereby disenga ging the pin 188 from the hook 191 (see Fig. 80). The arm 186 therefore drops (the arm 170 having previously dropped. as heretofore mentioned). ther-eb)7 through the arm 183l and spring 1832 raising the bar 18-1. raising the gravity latches 180 that are in engagement with the plungers 159. The plungers 159 under the pressure of the retracted springs 162 are thereupon forced out and striking the shanks or stems 157. of the type imprinting position. thereby recording on the paper carried by the platen the item that has been indicated by the indicator' wheels.

In the printing or recording of a total, it being understood that no'keys aie to be operated as in indicating or printinganitem, the operation is the same except that in this case the slide 128 is pushed to the left, thereby moving the rod 128 to the left so that the extension-1161 is in position to engage one of the openings 126 inthe gear 6 1 (see Figs. 20 Aand 21),. rilhe gears 61 have totaled and carried as heretofore described. This gear continually rotates so that there are a plurality of openings 126. it being understood that the operation of the member 1151 and consequentlyY the operation of the pin ion 106 and the type bars 95 are the same.

Up to the time that the operating handle is thrown the indicator wheels, both item and total, are prevented from rotating in a forward direction by the. pawl members 66 and 67. Upon the operation of theoperating handle 154, for .recording an item or total and consequently the rotation ofthe shaft 49, the cam'215 (see Figs. 2 and 5) is rotated.4l which forces the -upper end of the bell crank 237-288 forward and the lower end 238 rearward', and through the bar 250 and arm 251 the shaft 252 is rotated. This rotates the catches 258 so that they engage the pins 259 and the locking members 72, thereby locking the indicator wheels. lf no keys have been operated, as for example,'in the case of recording aftotal, when the operating handle is thrown the members would not be in engagement with the pins of the indicator wheels as in the caseof the key operating. By this arrangement. however. the indicator wheels are locked as well in taking ay total.

Movement of the arm 288 rotates the arm 217 through the bar 2164 and-the rotation of this bell crank 217-233 operates the latch 225, which coperates' with the pin 284 on the arm 283, vthereby rotating the shaft 69 (see Fig. )rotation of the shaft 69 raises the members 226 which coperate with the pins 227 on the latches 66 controlling the item indi ator wheels. which do not continuously rotatein one direction. The item indicator wheels are therefore released from the catches 66 but maintained against reverse rotation bythe locking members 72. As the arm 237 travels forward it engages ilnder the cam which coperates with the pin 286. The end210'of the, arm 287 and the cam member maintain the latches 66 up until theoperating handle has been returned rearward, so that the item indicator wheels mayl return back to Zero. By the time they have reached their Zero position the cam has slipped off the end of the eXtension 2-10 so that the catches 66 againdrop and engage the pins 68 of the item indicator wheels.` i

As the handle 151 is returned rearward the .shaft 149 is partially rotated in a reverse direction than before described, so that the arm 118 as it returns engages the pin 211 on the arm 210 and partially rotates the shaft 207 through bar 209 andarmY 208 (see Fig. 80) and this 'positively rotates the platen 98 through the vresiliently operated
